The 1991 Chevrolet Trucks R3500 came from the final years of Chevrolet's square-body heavy-duty pickup era, a time when one-ton trucks were expected to handle real work while still offering familiar trim distinctions like Cheyenne and Silverado. On this exact model, tire fitment centers on two radial 16-inch sizes: 235/85R16 for single-rear-wheel trucks and 215/85R16 for dual-rear-wheel versions. That makes the first decision less about brand heritage and more about identifying the truck's wheel setup correctly. Once that is settled, the focus shifts to proper load-minded sizing, sidewall presentation, and confirming wheel width and clearance before the truck goes back into service.
Which Tire Size Is Right for The 1991 Chevrolet Trucks R3500
The 1991 Chevrolet Trucks R3500 uses two primary tire sizes, and the difference follows the truck's rear-wheel configuration rather than a broad change in vehicle type. Both fitments are radial tires for 16-inch wheels, so the first step is confirming whether the truck is a single-rear-wheel model or a dual-rear-wheel version before comparing available tires.
235/85R16 is a metric radial size in which 235 identifies the nominal section width in millimeters, 85 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 1991 Chevrolet Trucks R3500, this size serves the single-rear-wheel Cheyenne and Silverado configurations. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving the truck a more assertive period-truck look than a plain black sidewall. This is the size to evaluate when the truck has the standard single-wheel rear axle and 16-inch wheels already in place.
215/85R16 is also a metric radial size, with a 215-millimeter nominal section width, an 85-series profile, radial construction, and a 16-inch rim diameter. On the 1991 Chevrolet Trucks R3500, this size applies to the dual-rear-wheel Cheyenne and Silverado models, where the narrower section helps suit the dually wheel arrangement. The practical choice here starts with confirming that the truck is still using its dual-rear-wheel setup and matching 16-inch wheels. That matters more than trim name alone, because dually fitment has different spacing and clearance considerations than a single-rear-wheel truck.
Sub-model fitment on the 1991 Chevrolet Trucks R3500 is straightforward once the rear-wheel configuration is identified. Cheyenne and Silverado trims share the same size within their wheel layout, while DRW models use a different tire size than single-rear-wheel trucks.

1991 Chevrolet Trucks R3500 Cheyenne
The 1991 Chevrolet Trucks R3500 Cheyenne uses the 235/85R16 radial size found on the single-rear-wheel version of this truck. Tire selection here centers on choosing the right 16-inch radial for the truck's working role, wheel-width compatibility, and preferred sidewall appearance.
The 1991 Chevrolet Trucks R3500 Cheyenne (DRW) uses the narrower 215/85R16 radial size associated with the dual-rear-wheel setup. Tire choice should begin with confirming the truck still has its dually wheels and proper wheel spacing before comparing replacement options.
The 1991 Chevrolet Trucks R3500 Silverado uses 235/85R16 radial tires in single-rear-wheel form, matching the same core fitment as the comparable Cheyenne setup. That means the main decision is selecting a tire within the correct size and checking wheel-width and service-use suitability.
The 1991 Chevrolet Trucks R3500 Silverado (DRW) uses 215/85R16 radial tires for its dual-rear-wheel configuration. That fitment should be treated as a dually-specific setup, so wheel arrangement and clearance deserve confirmation before any replacement tire is chosen.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:

Tire Size & Fitment
What tire size fits a 1991 Chevrolet Trucks R3500?
The 1991 Chevrolet Trucks R3500 uses two tire sizes: 235/85R16 and 215/85R16. The 235/85R16 size is used on Cheyenne and Silverado single-rear-wheel trucks, while 215/85R16 is used on Cheyenne (DRW) and Silverado (DRW) models with dual rear wheels.
The key is to match the tire size to the truck's actual wheel setup, not just the trim badge. A single-rear-wheel R3500 and a dual-rear-wheel R3500 do not use the same tire size, even though both ride on 16-inch wheels, so the rear axle configuration should be confirmed before replacing tires.
What size rim does a 1991 Chevrolet Trucks R3500 use?
Both primary tire sizes used on the 1991 Chevrolet Trucks R3500 fit a 16-inch rim. That applies to the 235/85R16 single-rear-wheel fitment and the 215/85R16 dual-rear-wheel fitment, so rim diameter stays the same even though the tire sizes differ.
Rim diameter is only part of the check on a heavy-duty truck. Wheel width and wheel type still matter, especially if the truck has been converted, restored with replacement wheels, or altered for service use, so the actual wheel dimensions should be verified before mounting a new tire.
Do all 1991 Chevrolet Trucks R3500 sub-models use the same tire size?
No. Cheyenne and Silverado single-rear-wheel models use 235/85R16, while Cheyenne (DRW) and Silverado (DRW) models use 215/85R16. The difference is tied to whether the truck is a standard rear-wheel setup or a dual-rear-wheel configuration.
That makes sub-model identification important, but the wheel arrangement is the real deciding factor. A trim name alone is not enough if the truck has been changed over the years, so checking whether it is still SRW or DRW is the safest way to narrow the correct tire size.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1991 Chevrolet Trucks R3500?
Start with the correct application, since 235/85R16 belongs on the single-rear-wheel 1991 Chevrolet Trucks R3500. After that, compare construction, load-minded specifications, rim-width compatibility, and the tire's intended use, especially if the truck still sees hauling, towing, or mixed on-road and unpaved service.
Appearance can matter too, particularly on a preserved square-body truck. The available 235/85R16 product includes a BFGoodrich All-Terrain T/A KO2 radial with raised white letters, so the choice is not just about size but also about whether that tread style and sidewall presentation suit the truck's work role and visual character.
What sidewall styles are available for 1991 Chevrolet Trucks R3500 tires?
Among the currently available options for this fitment, 235/85R16 is offered with an RWL sidewall, meaning raised white letters. That gives the 1991 Chevrolet Trucks R3500 a more aggressive truck-style presentation than a plain black sidewall and can noticeably change the vehicle's finished look.
Sidewall style should still come after the basic fitment checks. The correct size, proper wheel match, and intended use matter first, then the owner can decide whether a raised white letter look fits the truck's restoration direction, period-style appearance, or practical working-truck personality.
What brands offer tires for the 1991 Chevrolet Trucks R3500?
BFGoodrich is available in the 235/85R16 fitment used on single-rear-wheel 1991 Chevrolet Trucks R3500 trucks. That product is part of the All-Terrain T/A KO2 line and is built as a radial tire for a 16-inch wheel.
Brand should be considered alongside the rest of the tire's specifications rather than by name alone. On a one-ton truck, the better comparison points are the exact size, the wheel-width range, the sidewall style, the load specification, and whether the tire's tread and construction suit how the truck will actually be driven.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Chevrolet Trucks R3500?
A period-style choice starts with the correct original-style fitment for the truck's configuration: 235/85R16 for single-rear-wheel models and 215/85R16 for dual-rear-wheel versions. Keeping the proper size and 16-inch rim relationship does more for the truck's stance and visual balance than choosing an eye-catching tread alone.
From there, the right tire depends on whether the goal is a work-truck presentation, a preserved driver, or a more assertive late-era truck look. Owners chasing exact restoration details should also compare surviving photos, factory literature, or marque references before treating any available brand or sidewall treatment as a precise originality match.
How does tire construction affect the appearance of a restored 1991 Chevrolet Trucks R3500?
On this truck, primary fitment is radial, so the overall look is tied more to size, tread character, and sidewall style than to a bias-ply-versus-radial decision. A 1991 Chevrolet Trucks R3500 restored with the proper radial size will generally look more settled and authentic to its era than one wearing an incorrect profile.
Appearance still changes noticeably with sidewall treatment and tread design. A raised white letter all-terrain tire creates a tougher, more recreational truck impression, while a more restrained sidewall would present differently, so the final choice should match the truck's intended personality rather than relying on size alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Chevrolet Trucks R3500?
Yes. Changes such as aftermarket wheels, altered wheel width, suspension modifications, axle swaps, or conversion between single-rear-wheel and dual-rear-wheel setups can all affect tire fitment on a 1991 Chevrolet Trucks R3500. Even when the rim diameter remains 16 inches, the correct tire size may no longer match the truck's actual hardware.
A modified truck should be checked carefully before ordering replacements. Wheel width, wheel spacing, rear-wheel configuration, and clearance at the fenders and suspension all matter, especially on a one-ton truck that may still carry weight, so the current setup deserves inspection rather than relying only on original application.
What should I inspect before driving a 1991 Chevrolet Trucks R3500 on new tires?
Before road use, inspect the wheels for damage or mismatch, verify the tire size against the truck's SRW or DRW configuration, and check basic tire condition after mounting and inflation. Lug hardware, valve stems, and visible clearance around the suspension and body should also be reviewed before putting the truck back into service.
A heavy-duty pickup can mask problems until it is loaded or driven at speed, so a short initial test drive is wise. During that first drive, watch for vibration, rubbing, unusual steering feel, or uneven tracking, then recheck air pressure and look over the tire sidewalls and tread once the truck returns.
How should tires on a collector-era 1991 Chevrolet Trucks R3500 be maintained?
Tires on a collector-era 1991 Chevrolet Trucks R3500 should be checked regularly for pressure loss, uneven wear, sidewall cracking, cuts, bulges, and any signs of aging from long storage. A truck that is driven infrequently still needs routine inspection, because time and storage conditions can degrade tires even when tread remains deep.
Good maintenance also includes keeping the truck stored away from prolonged sunlight, excess moisture, and ozone sources such as electric motors or compressors. Periodic movement helps prevent flat spotting, and any truck that still works for a living should have its tires reviewed more often because load, heat, and mileage raise the stakes.
